Access To C Drive On Specific Computer Denied

I am the administrator for the whole system (network) and I have done something by accident (in active directory) which is preventing one of my computers on the network (webdev computer) from accessing it's own C drive (access denied). Furthermore, when I am logged into the Windows server 2008 as "Administrator", I look under "Computer" and I see the "C on WEBDEV" drive, but even when I click on it in there, it denies me access.I have access to everything else except for that drive.P.S. When I am logged in as a "user" or as "administrator" on the WebDev computer and look at the C drive, there is an icon with 2 people in it (I am assuming this is an icon for permissions), and I am denied access.

What I think happened is that the "owner" of the "win7" folder within the WebDev C drive was changed by accident (therefore affecting access to the whole C drive for any user on the WebDev computer). However, when I try and change the "owner", it will not allow me to (it says, "you do not have permission to view or edit this objects permission settings")

I tried logging in as WEBDEV\kris (which would be locally), but I could not get in.

I can only log onto the WEBDEV computer by using ABCSOLUTIONS\kris. I cannot even log in using WEBDEV\administrator, but I can log in using ABCSOLUTIONS\administrator (still do not have permissions to access the local C drive though).
